Crackle noise from high-speed free-shear-flow turbulence
… pressure signals reproduce the distinct crackle-like features observed with relatively flat shock-like waves, with sharp, steep compressions followed by weaker, rounded expansions. Their corresponding pressure skewness for $M\gtrsim2.5$ exceeds the level $S_k(p')\gtrsim 0.4$ associated …

The use of computer aided lung sound analysis to characterise adventitious lung sounds: a potential outcome measure for respiratory therapy
… second study). The intra-subject reliability of crackle frequency (f) within each session was found to be ‘good’ to ‘excellent’, estimated by the Analysis of Variance, Intraclass Correlation Coefficient, Smallest Real Difference and Bland and Altman 95% limits of agreement. Crackle initial …

Quantifying crackles in the lung of smoking and non-smoking young adults
Crackle sounds are associated with a variety of lung disorders. Smoking is also associated with many of the changes in the lung and airways leading to crackles. However, studying crackles as an indication of pathologic changes related to cigarette smoking in the lung is an underdeveloped area of …

Coalescence of nonlinear acoustic waves, with application to supersonic jet noise
… the observation of steepened Mach waveforms and crackle close to a lab-scale, Mach 3 jet flow in prior studies, which contradicted theoretical predictions for that jet. A numerical model based on the Khokhlov–Zabolotskaya–Kuznetsov (KZK) nonlinear wave equation is developed to demonstrate that …

Dynamic Primitives in Human Manipulation of Complex Objects
… interactions with flexible objects: minimum crackle of object (MCO) and dynamically constrained minimum jerk of hand (DCMJH). These models fail to reproduce human subject data in two ways: experimental hand velocities take on asymmetric bimodal profiles with shorter move durations, while the …
